Arizona State Retirement System, Phoenix, hired NorthPoint Capital to manage $140 million in active domestic midcap growth equities, said Gary Dokes, CIO. The board of the $23 billion system approved the search committee recommendation at a meeting Friday. Funding will come from reducing a roughly $340 million internally managed S&P 400 MidCap enhanced index portfolio. R.V. Kuhns assisted with the shortlist search.
